Logging before writing to disk is necessary for atomicity and durability. System can crash in the middle of directly writing to disk. Hence Write-ahead logging (WAL) ensures that, any change is written to log before applying to the actual system. In case a crash, database system can come back and check what was supposed to be done and accordingly recover from the crash by redoing/undoing. https://en.wikipedia.org/wiki/Write-ahead_logging

Thank you for your comments. I am editing the post.
